In-N-Out is a privately-owned hamburger fast food chain located in California, Arizona, and Nevada. It's simple menu has remained unchanged since the restaurant's extablishment in 1948. There are also "secret" item specials, variations of the basic menu that are not listed on the menu nor advertised.

Hamburger chain in California that everyone in that state claims is the best burger chain in the world. In reality, it is pretty average. It is not 'bad', but it is not as good as Jack-in-the-Box.
Bill: Hey, there is an In-n-Out burger here.
Ted: Yeah, lets ask them where the nearest Jack-in-the-Box is.
